## What to fix first

## What the site tells visitors (Measured, not scored)
- **No English version declared.** Visitors from abroad, and assistants answering in English, read the page as it is. In Berlin, 8.8% of comparable sites declare one.

- **No structured data for the business.** (+15 points) Add schema.org JSON-LD for the business (Dentist, MedicalClinic, Physiotherapy or the closest type, with name, address, telephone and openingHoursSpecification). It is the one block every assistant reads first; the fix kit below has it filled in. Guide: https://directindex.org/guides/structured-data-restaurant
- **No online booking link on the website.** (+15 points) Agents find no link to follow on the site. If you take bookings or orders through a platform, link to it from the site so an agent can find it. Add an online appointment page on your own domain. Guide: https://directindex.org/guides/book-direct-on-your-own-website
- **No list of services and prices found.** (+7 points) Agents answer 'what do they treat and what does it cost' from directories instead. Add a page with services and prices as text and link it from the homepage. Guide: https://directindex.org/guides/menu-pdf-ai
- **No llms.txt.** (no points, still worth doing) Optional today, cheap to add: a short text file describing the business for language models. Guide: https://directindex.org/guides/llms-txt-for-a-business
